2014 version NiteCore I4 intellicharge universal smart battery charger for li-ion/imr/ni-mh/ni-cd the intellicharge I4 is a universal, automatic smart-charger compatible with almost all types of rechargeable batteries thus eliminating the need to own several chargers. The I4 is able to automatically Identify li-ion, ni-mh and ni-cd rechargeable batteries and apply an appropriate charging mode (constant charge current (cc), constant charge voltage (cv) and trickle charge). each of the i4's four microcomputer-controlled charging slots is capable of monitoring and charging batteries independently. Additionally, yellow and Blue power/charging status indicator lights could visibly indicate battery status and charging process. I4: the all-new highly advanced smart charger. It's as simple as insert, detect, and charge.
